“"Muhammad of Arabia ascended the highest Heaven and returned. I swear by God that if I had reached that point, I should never have returned." These are the words of a great Muslim saint, 'AbdulQuddës of Gangoh. In the whole range of Sufi literature it will be probably difficult to find words which, in a single sentence, disclose such an acute perception of the psychological difference between the prophetic and the mystic types of consciousness. The mystic does not wish to return from the repose of "unitary experience"; and even when he does return, as he must, his return does not mean much for mankind at large.”

Context: At the highest level of satori from which people return, the point of consciousness becomes a surface or a solid which extends throughout the whole known universe. This used to be called fusion with the Universal Mind or God. In more modern terms you have done a mathematical transformation in which your centre of consciousness has ceased to be a travelling point and has become a surface or solid of consciousness... It was in this state that I experienced "myself" as melded and intertwined with hundreds of billions of other beings in a thin sheet of consciousness that was distributed around the galaxy. A "membrane".

Notes from Devotional Authors of the Middle Ages (1873-1874)
Context: Where shall I find God? In myself. That is the true Mystical Doctrine. But then I myself must be in a state for Him to come and dwell in me. This is the whole aim of the Mystical Life; and all Mystical Rules in all times and countries have been laid down for putting the soul into such a state.
That the soul herself should be heaven, that our Father which is in heaven should dwell in her, that there is something within us infinitely more estimable than often comes out, that God enlarges this "palace of our soul" by degrees so as to enable her to receive Himself, that thus he gives her liberty but that the soul must give herself up absolutely to Him for Him to do this, the incalculable benefit of this occasional but frequent intercourse with the Perfect: this is the conclusion and sum of the whole matter, put into beautiful language by the Mystics. And of this process they describe the steps, and assign periods of months and years during which the steps, they say, are commonly made by those who make them at all.
